Actually I did a clean installation, inserted the two global posted by batiskaf and alain's ux and the 3d DAs are not seen both on the map but are at least highlighted in the DA signals alert menu in the skin menu.
Even if there is no way, at least for me, to hear the demo.
However, returning to the DA3d I think the problem is in the ux. And let me explain.
The functioning of the icons is linked to the name, but also to the icon file of the various countries inserted in the path ui_nexten / icon / sys
I realized that in the new ux driveralerts pongo has omitted to insert several file icons compared to the previous one. I have inserted in my miniskin (but you can do it directly in the driveralerts) the missing icon files and, at least for Italy, the DA3d have reappeared even in navigation.
Probably, without these file icons (which matches the right names of the da) the program will use those of the global_confg which, if named differently, make the standard icons appear.
